A CMOS Analog Cell and its applications in analog signal processing

This paper presents a core cell that can be reconfigured and combined with current mirrors to implement exponential, logarithmic, multiplier, divider and raise-to-power function circuits. The proposed circuit uses CMOS transistors operating in the strong inversion. The proposed circuits has been verified with the 0.8 μm CMOS technology by HSPICE simulations. The simulations results confirm the functionality of the proposed circuits. The proposed circuits paves the way for designing analog signal processors.
